Description

  The present invention relates to an improvement of an intercom system having a function of controlling an external device such as a fire detector.

  Conventionally, an intercom system for an apartment house has been developed that has a function of outputting an alarm and prompting residents to evacuate when an earthquake occurs.

  For example, the following Patent Document 1 discloses a collective entrance machine, a living room master machine, an earthquake recognition device for recognizing and transmitting earthquake information such as seismic intensity and epicenter by the occurrence of an earthquake, and a controller for controlling them. In the intercom system for multi-dwelling houses configured as described above, it is described that the controller transmits the earthquake information to the living room parent machine, and the living room parent machine notifies the earthquake information.

  In Patent Document 2, an alarm sound is generated from a speaker of a room master unit that allows a call to and from an entrance handset, and displayed on a monitor, so that an alarm is issued for earthquake information transmitted from the outside. In addition, in the event of an earthquake, an intercom system is described in which an ignition device is extinguished to prevent a fire from occurring, and lighting lamps are turned on, blinds are lifted, and electric locks are unlocked.

Further, in Patent Document 3, a recovery operation is performed when a predetermined time has elapsed after the end of the earthquake, and a single reciprocal operation is performed at each floor stop by a low-speed automatic operation from the stop position. At that time, sound pressure check is automatically performed by an intercom. There is described an elevator operating device that is checked automatically and automatically recovers if abnormal sound and running time are within specified values, and recovers based on manual recovery determination at a maintenance center if abnormal sound is present.

  However, in the intercom systems disclosed in Patent Documents 1 and 2, although an occupant can be warned in the event of an earthquake and an external device connected to the resident base unit can be controlled, the external device breaks down due to the earthquake. I couldn't know if I did it. Patent Document 3 teaches a technique for knowing whether or not an external device has failed due to the influence of an earthquake, and only uses an intercom in the elevator for an elevator operation test after an earthquake. Absent.

  Therefore, an object of the present invention is to provide an intercom system that can immediately know whether or not an external device connected to an interphone master unit has failed after an earthquake.

In order to solve the above-described problems, the present invention provides an earthquake receiver that acquires earthquake occurrence information, an interphone master unit that has a function of testing and diagnosing a predetermined external device, and is connected to the earthquake receiver. When the interphone master unit receives the earthquake occurrence information from the earthquake receiver, the interphone master unit is detected by executing a test of the external device after a predetermined time has elapsed. In addition, an external device test unit for notifying the abnormality of the external device is provided, and the test includes at least a disconnection test of the sensor line .

  In the above, the earthquake receiving device may be configured to receive an emergency earthquake warning as the earthquake occurrence information.

  The external device test unit includes a storage unit that stores a functional state of the external device, and the external device detected by the test when the earthquake occurrence information is received. Only the abnormality may be notified.

  The intercom system may further include a communication device that transmits an abnormality of the external device detected in the test to a pre-registered communication device.

  The external device test unit has a function of storing the functional state of the external device, determines an abnormality of the external device detected in the test, and the intercom system receives the earthquake occurrence information. In this case, a communication device may be further provided that transmits only the determined abnormality of the external device to a pre-registered communication device.

In the present invention, when a predetermined time has elapsed since the earthquake receiving device acquired the earthquake occurrence information, the interphone master unit performs at least a sensor line disconnection test as a test of the external device, and detects the detected abnormality. So that the sensor line breakage due to the earthquake can be immediately known.

  In particular, in the configuration in which the earthquake receiving device receives the earthquake early warning as the earthquake occurrence information, the structure is simple because the earthquake occurrence information can be easily acquired. In addition, since there is no need to install a seismometer in the system, the cost is low.

  In addition, it is possible to distinguish whether or not the failure is caused by an earthquake in a configuration in which only a new abnormality of an external device detected by a test performed when a predetermined time has elapsed after acquiring earthquake information is detected. it can.

  In addition, in the configuration that transmits the abnormality of the external device detected by the test executed when the predetermined time has passed since the earthquake information was acquired to the pre-registered communication device, the influence of the earthquake can be known even when away from home. it can.

  In addition, in a configuration in which only a new abnormality of an external device detected by a test performed when a predetermined time has elapsed after acquiring earthquake information is transmitted to a pre-registered communication device, the message to be transmitted has a small capacity. Therefore, it is suitable when the communication device is a mobile phone.

Embodiments of the present invention will be described below with reference to the drawings.
Here, FIG. 1 is a connection diagram of devices constituting an intercom system for an apartment house to which the present invention is applied, FIG. 2 is a block diagram illustrating a schematic configuration of an interphone master unit to which a fire detector is connected, and FIG. It is a flowchart for demonstrating test operation | movement of the external apparatus by a machine.

  The intercom system 1 shown in FIG. 1 is installed at an intercom master unit 11 installed in each dwelling unit of a housing complex, a call / video control panel 12 installed in a manager's room, an alarm monitoring panel 13, and a common entrance. And a lobby interphone 14 with a camera.

  The intercom master unit 11 has a function of controlling a predetermined external device 2. Examples of the external device 2 include a fire detector 2 # 1, a security sensor 2 # 2, a water leak sensor 2 # 3, Lock 2 # 4, gas sensor 2 # 5, call sensor 2 # 6, and emergency sensor 2 # 7 are connected.

  The intercom base unit 11, the call / video control panel 12, the alarm monitoring panel 13, and the lobby intercom 14 are connected to each other by a call signal line, a video signal line, a control signal line, and the like. The branching unit 15 is a device for branching a call signal line, a video signal line, a control signal line and the like derived from the call / video control panel 12 toward the intercom master unit 11 of each dwelling unit.

  The alarm monitoring panel 13 is connected to an earthquake receiving device 16 that acquires earthquake occurrence information. The earthquake receiving device 16 may detect the occurrence of an earthquake by a seismometer, but may be configured to receive earthquake occurrence information from other devices. Moreover, the structure which receives the earthquake early warning which a meteorological agency announces at the time of an earthquake may be received as earthquake occurrence information. Immediately after the occurrence of an earthquake, the Earthquake Early Warning gathers observation data captured by a seismometer near the epicenter immediately to the Japan Meteorological Agency, identifies the location of the epicenter and the magnitude of the earthquake (magnitude) by computer analysis, Estimating the arrival time of major motions in each location and their seismic intensity, and sending emergency earthquake bulletins to receivers in each location. If this emergency earthquake bulletin is used as earthquake occurrence information, earthquakes (major motions) will occur. It is safer because it can output an alarm.

  In addition, when using an earthquake early warning as earthquake occurrence information, it is also possible to register location information in the earthquake receiving device 16 in advance and predict a more accurate seismic intensity level from the information and the contents of the emergency earthquake early warning signal. Good.

  The alarm monitoring panel 13 is also connected with a communication device 17 for transmitting an emergency message or the like indicating that an abnormal situation has occurred in a dwelling unit to a pre-registered communication device 32 through an external network. The communication device 17 can be configured by a modem or the like, for example. Although the format of the emergency message is not limited, for example, an e-mail is preferable because a resident's mobile phone can be designated as the destination communication device 32. The report monitoring panel 13 having such a configuration includes a storage unit for pre-registering a mail address of a transmission destination corresponding to each dwelling unit, and a mail transmission unit for automatically generating an e-mail describing an emergency message. Prepare. Note that the communication device 32 may set, for example, a fax machine or a personal computer in addition to the mobile phone.

  The basic function of the intercom system 1 will be described. When a call operation is performed by designating a dwelling unit number on the lobby interphone 14, the call / video control panel 12 calls the designated interphone master unit 11, and the interphone master unit 11 is called. When a response operation is performed, a communication path is formed between the interphones 11 and 14 to perform a mutual call. During this mutual call, an image of a visitor photographed with the camera of the lobby intercom 14 is displayed. Displayed on the monitor screen of the machine 11.

  In addition, the interphone master unit 11 controls and monitors the external device 2 to output a voice alarm and notify the alarm monitor panel 13 when an abnormality occurs, and the alarm monitor panel 13 issues a voice alarm from the interphone master unit 11 of the neighboring dwelling unit. Output or transfer to an external organization such as a fire department. At this time, an emergency message for notifying the occurrence of an abnormality may be transmitted to the pre-registered communication device 32 through the alarm monitoring panel 13 and the communication device 17. The interphone master unit 11 includes a test switch for instructing a test operation of the external device 2, and when the switch operation is performed, the designated external device 2 is subjected to a test operation, and the test result is displayed. In addition, it has a function to notify by voice or display.

  Further, as a feature of the present invention, when the earthquake receiving device 16 acquires earthquake occurrence information, the alarm monitoring panel 13 notifies the occurrence of an earthquake to the interphone master unit 11 of each dwelling unit, and an audio alarm is issued from the interphone master unit 11. The evacuation is urged to output, but when a predetermined time (for example, 5 minutes) has passed, the interphone master unit 11 executes the test of the external device 2 and outputs the detected abnormality as a voice or the monitor screen To display. Thereby, it is possible to immediately detect the external device 2 that has failed due to the earthquake. In the configuration using the emergency earthquake warning as the earthquake occurrence information, the test may be executed after the arrival of the S wave. In addition, the intercom master unit 11 notifies the alarm monitoring panel 13 of the abnormality of the external device 2 detected in the test, and causes the alarm monitoring panel 13 to display and output the abnormality. Thereby, it becomes possible to grasp the state of each dwelling unit on the alarm monitoring panel 13.

  Further, the alarm monitoring panel 13 may automatically generate an emergency message reporting an abnormality of the external device notified from the interphone master unit 11 and transmit it to the pre-registered communication device 32 through the communication device 17. In this way, the resident who is out can learn the effects of the earthquake of the dwelling unit. Note that the intercom base unit 11 may include a storage unit for registering a transmission destination address in advance and a mail transmission unit for generating an emergency message, and generate the emergency message.

  Note that the interphone master unit 11 has a storage unit 11d for storing the functional state of the external device 2 so that only a new abnormality of the external device 2 detected in this test is determined and notified. Good. In this case, it can be determined whether or not the failure of the external device 2 is caused by an earthquake.

  In this configuration, an emergency message that reports only a new abnormality of the determined external device 2 may be generated and transmitted. By doing so, the emergency message can be of a small capacity, which is suitable when the communication device 32 is a mobile phone.

  The interphone master unit 11 shown in FIG. 2 is rewritable with a device control unit 11a composed of a microcomputer, an external device control unit 11b composed of a fire detection circuit, and an external device test unit 11c that tests the external device 2. The fire detector 2 # 1 is connected to the storage unit 11d as an example of the external device 2. In addition, a monitor screen (not shown) is provided, and an image of a visitor photographed by the camera of the lobby intercom 14 and a test result of the external device 2 can be displayed.

  As described above, the external device test unit 11c executes the test of the external device 2 when a predetermined time has elapsed since the earthquake receiving device 16 acquired the earthquake occurrence information. Conduct a disconnection test based on the resistance value. In addition, the storage unit 11d stores a test result performed last time, and by comparing the stored content with the latest test result, a newly detected abnormality can be determined. Specifically, the test of the external device 2 may be a sensor line disconnection test by a fire detection circuit, acquisition of status information of the external device 2 by polling, etc., but there is no particular limitation.

  Next, an example of the test operation of the external device 2 by the intercom base unit 11 will be described according to the flowchart of FIG.

  In this example, first, the earthquake receiving device 16 acquires earthquake occurrence information and notifies the alarm monitoring panel 13 of the earthquake occurrence information (steps 101 and 102).

  Receiving this, the alarm monitoring panel 13 notifies the earthquake occurrence information to each of the intercom master units 11 all at once (step 103).

  When receiving the earthquake occurrence information from the alarm monitoring panel 13, the intercom base unit 11 immediately outputs a voice alarm to prompt the resident to evacuate (step 106). Then, when a predetermined time has elapsed after starting the measurement of the elapsed time from this time point, the test of the external device 2 is executed, the newly detected abnormality of the tested external device 2 is determined, and the determined abnormality is notified, Further, the abnormality is notified to the alarm monitoring panel 13 (steps 107 to 110).

  Upon receiving the notification, the alarm monitoring panel 13 generates an emergency message reporting the abnormality of the external device 2 notified by the interphone master unit 11, and transmits the message to the pre-registered communication device 32 ( Steps 104-105).

  In the above description, the intercom system 1 for multi-dwelling houses has been described as an example. However, the idea of the present invention, that is, the interphone master unit 11 is a test of the external device 2 when a predetermined time has elapsed after the occurrence of an earthquake. The idea of performing the notification and notifying the detected abnormality of the external device 2 can also be applied to an interphone master unit for a detached house. In this case, the earthquake receiving device 16 and the communication device 17 may be configured to be directly connected to the interphone master unit 11.
